I got this memory foam mattress (queen size) for a guest bedroom in our home. Upon delivery I was pleasantly surprised at how compacted it was and the relatively small size of the box that it was in.  I'm 5'3", 125# and I was able to unbox it and unwrap it by myself.  I really like that it has a zippered cover so that it can be washed if needed. It seems really comfortable and well constructed. It's only been 10 min since I took it out of the shrink wrap and it's already about 7.5" deep. I'm assuming will continue to expand over the next 24 hours to the full 8". Very pleased with this mattress so far!
